It is interesting to here ask attention to the opinions entertained and expressed by those whose situation and experience have qualified them to speak with authority: "The duty constitutes the price of the whole mass of the article in the market. It is substantially paid on the article of domestic manufacture, as well as that of foreign production" (John Quincy Adams). "I said it, and I stand by it, that as a general rule the duties paid on imports operate as a tax upon the consumer" (John Sherman). Mr. Blaine, in his Twenty Years in Congress, says, speaking of the increase of duties on imports by the tariff act of July 14, 1862, that it "shut out still more conclusively all competition from foreign fabrics. The increased cost was charged to the consumer." Mr. McKinley, in 1890, in a report introducing a bill for revision of the tariff of the United States, in the direction of increased rates of duties on imports, said it was not the intent of the bill "to further cut down prices," that the people were "already suffering from low prices," and would not be satisfied "with legislation which will result in lower prices." In an elaborate opinion given by the New York Court of Appeals in 1851 (see vol. iv, New York Reports), in which there was no suspicion of any issue of free trade or protection, the courts, in carefully considering the relative powers of the legislature and the judiciary in respect to taxation, assumed the proposition that "_all duties on imported goods are taxes on the class of consumers_" to be in the nature of a self-evident truth or economic axiom. Henry Clay, in a celebrated speech in the United States House of Representatives in 1833, in advocacy of a protective tariff policy, candidly admitted that "in general it may be taken as a rule that the duty upon an article forms a portion of its price." But he subsequently qualified such admission by claiming that it does not follow that any consequent enhancement of its price is a tax on consumers, inasmuch as "directly or indirectly, in one form or another, all consumers of protected articles, enhanced in price," will get an equivalent. But this may be equally affirmed of all necessary and equitable taxation, and does not in any way antagonize the theory that the final incidence of the class of taxes under consideration falls on consumption.
